Update app version

Hi there,
I have created a UI kit app and uploaded it to production. When I release newer versions, the instance that uses the app in production does not get updated. How can I do that?

There is no update option in the UPM and also not in the Developer console. For instance, image taken from developer console:

Also when I install and re-install the app it does not get updated.

I should clarify that it is a shared app that was not published to the market place.

Thanks,
Talia
